S-99607A318 M10 x 20 mm Thumb Screws

Key Features & Benefits at a Glance

• Effortless hand-tightening with a precision knurled 19.5mm head for superior grip in high-vibration or gloved-hand applications.
• Excellent corrosion resistance thanks to 18-8 stainless steel construction, ensuring long-term reliability in harsh or humid environments.
• High mechanical strength with 80,000 psi tensile strength and Rockwell B85 hardness for dependable performance under load.
• Quick and secure fastening from the fully threaded M10 x 1.5 mm coarse thread design, providing maximum engagement and reducing assembly time.
• Precise and reliable fit with Class 6g thread tolerance, ensuring consistent compatibility with standard metric nuts and tapped holes.
• Stable seating and alignment due to the integrated flared collar, which helps distribute load and prevents over-tightening.
• Safe for regulated industries as it is fully compliant with RoHS 3 and REACH environmental standards.

Professional Applications & Engineering Value

This M10 thumb screw is engineered to solve common industrial fastening challenges where tool-free access, corrosion resistance, and repeated adjustability are critical. The 18-8 stainless steel material provides inherent resistance to rust and oxidation, making it ideal for outdoor equipment, marine hardware, and electronic enclosures exposed to moisture. The fully threaded design and coarse thread pitch enable rapid installation and removal, reducing maintenance downtime in assembly lines, machinery guards, and panel systems. The knurled head offers a non-slip surface that remains functional even with oily hands or protective gloves, enhancing operator safety and efficiency. Its flared collar adds stability, minimizing the risk of cross-threading and damage to softer materials, which is essential for precision fixtures and repeated disassembly in prototyping or testing setups.
